The National Institute of Standards and Technology (NIST) today announced the winner of its five-year competition to select a new cryptographic hash algorithm, one of the fundamental tools of modern ...

IPsec incorporates several cryptographic operations to ensure message authenticity, data integrity, and sender nonrepudiation. In this section we will describe the mechanics of these cryptographic ...

An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

This standard specifies secure hash algorithms, SHA-1, SHA-224, SHA-256, SHA-384, SHA512, SHA-512/224 and SHA-512/256. All of the algorithms are iterative, one-way hash functions that can process a ...
